Abstract

Based on the analysis of variations in the five day mean OLR and low-level wind fields (1,000 and 850hPa), intra- seasonal changes in the convective activity in Mexico are documented. The results show that as the convection over northwestern Mexico tend to increases from the middle of June, the opposite tendency is visible in the southern part of the country, the Caribbean, Central America, and the eastern tropical Pacific, where a period of less convection, locally termed "canicula", occurs in the middle of the rainy season. Changes in the intensity of low-level wind over Central America and the eastern Pacific are consistent with the onset and evolution of the rainy season over the studied region.
